摘　　要：近年来,随着互联网的不断发展,虽然当前现有网络基础设施基本上已经能满足互联网应用对网络传输的基本要求,但仍然不可避免的会出现延迟、丢包、抖动等。应用程序为了能够正常通信,就需要合理应对这些网络故障,在程序编写初期就应该选择合适的网络传输协议,从而让应用程序在真实环境中有更好的表现。本文设计了一种基于连接质量的传输层协议测试系统,利用TC等工具来模拟不同的网络状况,来评估在不同网络状况下,不同传输层协议的表现差异。开发人员可以使用本系统来选择合适的传输层协议进行网络应用的开发。In recent years,with the continuous development of the Internet,although the current existing network infrastructure can basically meet the basic requirements of Internet applications for network transmission,delays,packet loss,jitter,etc.are inevitable.In order to communicate properly,the application needs to properly deal with these network failures.At the beginning of the program,the appropriate network transmission protocol should be selected to make the application perform better in the real environment.This paper designs a transport layer protocol test system based on connection quality,and uses TC and other tools to simulate different network conditions to evaluate the performance differences of different transport layer protocols under different network conditions.Developers can use this system to select the appropriate transport layer protocol for network application development.
